I thought some folks might enjoy seeing dyno results from an E85 tuned and daily driven EKK...

I recently got my combination together (K20A2, AEM CAI, RCrew header, 2.5" exhaust, Hondata) and I had done just about all of the street tuning I could and was ready for some dyno time. Some good friends of mine (THANK YOU cp-e!) basically let me spend the evening flogging their MD-500 Mustang Dyno, which is a load bearing dyno so I was able to dial in my ignition advance and cam timing pretty well. I don't know the exact total, but I think we did somewhere in excess of 50 runs to get all the maps correct, and I ended up using more than a half tank of E85, haha. It was a good time!

My dyno graph:

Anyway, the car ended up making 205whp/148wtq, and on this dyno that's pretty respectable. To put that in perspective, a Mazdaspeed3 with an intake and downpipe made 210whp on that same dyno (dotted lines was before the tune, solid was after).

And for grins, here's an article Import Tuner did on the Mazdaspeed6 (same engine as MS3 but with all wheel drive) using the cp-e dyno:

Because the MD-500 is bad ass, I was able to run a simulated quarter mile on it. Before anyone says it, yes, I realize this is not a real quarter mile. I have twice the contact patch on the front tires, and wheel hop is a non-issue. I look at this as a best-case scenario of what the car would run if it were properly setup for track duty (i.e. what the power is capable of). Regardless, it was a fcuking lot of fun!!

For those that want to use E85 for their own vehicles, getting it setup for alcohol was actually really easy. I was expecting a lot of trial and error just in order to get the thing started using canned gas maps, but all I did was add like 30% fuel everywhere, and that was good enough to get the car running. From there I just dialed in the part throttle operation, and then moved to WOT. I also had to tweak the cranking pulse-width because when the engine was cold (ECT under 70 degrees or so) it took a few more cranks to catch. If anyone wants to take a look at my map or wants some help I'm happy to share what I've learned so far.

Overall I'm super happy with the car. It starts up every morning, idles smooth, and gets great gas mileage. And when I want to, I can open it up and burn up the back roads. What a great setup!!
